Hi, I have now got the code to assemble and I am considering how to adapt it for linking and create a linker file. I think I have applied your suggestion...

Thanks a lot its actually for a project... I am also having a hard time figuring out the exact process with a real time interrupt. is this a good understanding...
Exactly... but you also have to make sure that, in addition to the setting of the registers which will initialize and end a real-time interrupt run... you have...

Thanks once again Edward. I did not need to remove all the "offset 0" statements, although I have, I only need to remove them in the situation where a label...
Regarding INITRM. I played around it in hope to find a difference between word aligned stab >INITRM, misaligned stab >INITRM, aligned and misaligned stab...
Thanks again, I am using the mini-dragon evaluation board. I am still sketchy on what actually triggers the real time interrupt since I am coding in c in my...
... I don't know why anyone is worried about this. I thought the documents were pretty clear that for S12 there is no alignment requirement for _execution_....
... I like the dragon boards too. Hopefully this explanation helps with your RTI questions... The only reason we need an RTI module in the mcu is that it works...
Your comment is 100 % right on, Jeff Smith... I did actually use the RTI to receive data from a medical sensor i was working with. That sensor was sending data...

why is the output compare more accurate then the rti function. If you remember my problem I was trying to store bits in serially through a port and store the...

Hi All It is a goal that I set myself sometime ago and finally I can proudly present a first version of a BDM for the M9S12NE64. In fact it's not a BDM as such...
... Very cool! I'd love to see if this BDM can be modified to support a Coldfire target! The cheapest Coldfire BDM costs around $250, and that's for the most...
Does anyone tried piezo cable from measurement speicalities inc. to count and measure the speed of traffic using HCS12? The response of the sensor is so fast...
FYI the M52235 EVB is USD $299 and comes with the USB PE coldfire BDM and also a power-pack and the eval coldfire codewarrior etc. You can order direct online....

I would run the output of the cable into a high-impedance scaling, protected, and high-speed opamp to get the signal conditioned first, and then run the output...
Hello All, did anybody scrutinize closely why Freecale tells us to use at least (!) 400nF to decouple the 2,5V core voltage? Especially with the small 48 pin...
